Abstract

The cooling system are indispensable components for high power laser transmitter. The laser system ensures compact, lightweight, energy-saving is a major challenge in laser manufacturing. This paper presents a novel thermal design for our compact high peak power Yb:Er:glass laser. The cooling system is based on thermoelectric cooler with heat dissipation of the TEC’s hot side using vapor chamber, heat sink and fan. The finite element analysis is applied for temperature distribution simulation. The simulation model is calibrated by experiment results to ensure that the error is less than 6%. The laser with cooling system stably operates at the peak power of 1 MW, the repetition rates are tunable from 1 Hz to 20 Hz, and the operation temperature range is from -20 °C to 60 °C.
